EN 13138-3:2021 (E)
Introduction
The entire process of learning to swim is considered to include two stages:
— getting familiar with the water environment and movements in it, and
— acquiring skills in standard swimming strokes.
Buoyant aids for swimming instruction (in brief: swimming device(s)) are intended to assist users (in
particular children) to learn to swim. The design and purpose of the swimming devices are related to the
above stages.
Swimming devices are intended to give the user positive buoyancy in the water while maintaining the
correct body position for swimming. However, it should not be assumed that standard conformity of the
swimming devices will by itself eliminate the risk of drowning as this depends also on the behaviour of
the user and any supervision.
Although this document sets performance requirements to ensure that swimming devices perform
appropriately, it is essential that the swimming devices are used correctly and under constant and close
supervision. It is important to ensure that they are securely fitted to the appropriate size of user and that
when correctly fitted, they cannot become displaced. Swim seats however should allow immediate escape
in case of capsizing. Therefore, the use of these swimming devices is recommended to be restricted to
water out of standing depth of the user.
The highest degree of protection against drowning can only be achieved by using lifejackets. It is essential
that there is a clear distinction between swimming devices intended to preserve life and those which are
intended only to assist buoyancy for the user when learning to swim. As swimming devices are not life
preservers, they should only be used in swimming pools and other situations free from current, tides and
waves.
The bulk storage of some types of swimming devices could, under certain conditions, result in a potential
fire hazard. The perceived risk of such a hazard was evaluated against the actual risk to the user from
materials treated with certain known toxic fire-retardant chemicals. However, the fire hazard is less of a
problem to the user than the risk associated with the swimming devices being put in the mouth, especially
by children. For this reason, flammability requirements are not included in this document.
For the above reasons and to differentiate these swimming devices from aquatic toys, advisory safety
measures, including marking, warning notices and user instructions are included in this document.
The range both of the design and function of buoyant aids for swimming instruction varies considerably
and for this reason, the standard for swimming devices has been prepared in three parts, namely
swimming devices that are intended to allow the user to become familiar with water (passive user),
swimming devices that are worn (active user) and those swimming devices that are held by the user to
improve swimming strokes.
— Part 1 of this series is only for products that are securely attached to the body (Class B swimming
devices = for an active user). They are intended to introduce the user to the range of swimming
strokes.
— Part 2 of this series is for products that are held either in the hands or by the body (class C swimming
devices = for an active user) and are intended to assist with improving specific elements of the
swimming stroke. For adult beginners or more advanced users they can also be used for further
stages of the process to learn to swim.
— Part 3 of this series deals only with products (swim seats) to assist children up to 36 months in their
first attempts to learn to swim (i.e. to get familiar with the ―in-water-environment) and moving
through it. The child is positioned inside the buoyant structure, which provides buoyancy and lateral
support to the body, thereby keeping the child’s head above water level (class A devices = for a
passive user).

SIST EN 13138-3:2021
EN 13138-3:2021 (E)
Swim seats allow young children to experience the water environment and being moved through it.
Movements of lower limbs and arms are possible. The use of swim seats does however not replicate any
form of a correct swimming stroke.
Swim seats complying with this document provide a stable, floating position for a child sitting in the swim
seat and avoid entrapment in case of capsizing. Children in swim seats do however require very close
parental supervision. Overload beyond specified body mass, breaking waves and violent external forces
are remaining risks that can cause capsizing. Use of these devices in water that is of the child’s standing
depth will increase the risk of capsizing and will hinder or block the escape from the seat in case of
emergency.

5.1 General
Construction of a buoyant swimming device shall be such that it corresponds in terms of design,
dimensions, safety, strength and durability for its intended use. The requirements set out were chosen to
ensure compliance with these considerations. Where buoyant swimming devices are provided in several
components, the requirements apply to each of the components as specified in the relevant paragraphs
below.
Buoyancy may be provided by inherent buoyancy materials, by inflatable chambers or by both. Where
buoyancy is not inherent, swimming devices shall have a minimum of two independent chambers
safeguarding function and to allow the user to maintain the airway above water level at all times if one
chamber fails. A swimming device shall be only class A or class B or class C.
These products shall be manufactured in bright colours that are in contrast to the water surface so as to
be visible at all times and at any angle when in use. Wholly transparent or materials in any shade of
undecorated blue in the visible areas when in use are not acceptable.

prEN 13138-3:2018 (E)
Introduction
The entire process of learning to swim is considered to include two stages:
— getting familiar with the water environment and movements in it;
— acquiring skills in standard swimming strokes.
Buoyant aids for swimming instructions (in brief: swimming device(s)) are intended to assist users (in
particular children) to learn to swim. The design and purpose of the devices are related to the above
stages.
Swimming devices are intended to give the user positive buoyancy in the water while maintaining the
correct body position for swimming. However, it should not be assumed that standard conformity of the
devices will by itself eliminate the risk of drowning as this depends also on the behaviour of the user
and any supervision.
Although this European Standard sets performance requirements to ensure that swimming devices
perform appropriately, it is essential that the devices are used correctly and under constant and close
supervision. It is important to ensure that they are securely fitted to the appropriate size of user and
that when correctly fitted, they cannot become displaced. Swim seats however should allow immediate
escape in case of capsizing. Therefore the use of these devices is recommended to be restricted to water
out of standing depth of the user.
The highest degree of protection against drowning can only be achieved by using lifejackets. It is
essential that there is a clear distinction between devices intended to preserve life and those which are
intended only to assist buoyancy for the user when learning to swim. As swimming devices are not life
preservers, they should only be used in swimming pools and other situations free from current, tides
and waves.
The bulk storage of some types of swimming devices could, under certain conditions, result in a
potential fire hazard. The perceived risk of such a hazard was evaluated against the actual risk to the
user from materials treated with certain known toxic fire retardant chemicals. However, the fire hazard
is less of a problem to the user than the risk associated with the swimming devices being put in the
mouth, especially by children. For this reason, flammability requirements do not apply to this European
Standard.
For the above reasons and to differentiate these devices from aquatic toys, advisory safety measures,
including marking, warning notices and user instructions are included in this standard.
The range both of the design and function of buoyant aids for swimming instruction varies considerably
and for this reason, the standard for swimming devices has been prepared in three parts, namely
devices that are intended to allow the user to become familiar with water (passive user), devices that
are worn (active user) and those devices that are held by the user to improve swimming strokes.
Part 1 of this European Standard is only for devices that are securely attached to the body (class B
devices = for an active user). They are intended to introduce the user to the range of swimming strokes.
This part 1 of prEN 13138 is applicable only in connection with part 4 of prEN 13138.
Part 2 of this European Standard is for devices that are held either in the hands or by the body (class C
devices = for an active user) and are intended to assist with improving specific elements of the
swimming stroke. For adult beginners or more advanced users they can also be used for further stages
of the process to learn to swim.
Part 3 of this European Standard deals only with swim seats to assist children up to 36 months in their
first attempts to learn to swim (i.e. to get familiar with the „in water environment― and moving through
it). The child is positioned inside the buoyant structure, which provides buoyancy and lateral support to
the body, thereby keeping the child's head above water level (class A devices = for a passive user).

oSIST prEN 13138-3:2018
prEN 13138-3:2018 (E)
Swim seats allow young children to experience the water environment and being moved through it.
Movements of lower limbs and arms are possible. The use of swim seats does however not replicate any
form of a correct swimming stroke.
Swim seats complying with this standard provide a stable, floating position for a child sitting in the
swim seat and avoids entrapment in case of capsizing. Children in swim seats do however require very
close parental supervision. Overload beyond specified body weight, breaking waves and violent
external forces are remaining risks that can cause capsizing. Use of these devices in water that is of the
child‘s standing depth will increase the risk of capsizing and will hinder or block the escape from the
seat in case of emergency.
Buoyant swimming aids should be only a class A or a class B or a class C device.
Part 4 of this European Standard deals with in-water performance testing for class B devices and
provides objective methods of measuring the lifting and turning capacity of a swimming device by
applying test manikins of various sizes. It is applicable only in connection with part 1.

1 Scope
This part 3 of EN 13138 specifies safety requirements for design, sizing, materials, strength and in-
water performance as well as provisions for marking and the information supplied by the manufacturer
for swim seats. It also specifies the relevant test methods. This standard is not applicable to products
covered by EN 13138-1 and -2.
This part 3 of EN 13138 applies only to devices into which the user is placed and which have either
inherent buoyancy or can be inflated or a combination of both. It only applies to class A devices
intended to introduce the user to the water environment. These devices are only intended for children
aged up to 36 months with a body mass less than or equal to 18 kg. It does not apply to class B or class C
devices, to pull buoys, lifebuoys, buoyancy aids, lifejackets or aquatic toys.

5 Safety requirements
5.1 General
Construction of a buoyant swimming device shall be such that it corresponds in terms of design,
dimensions, safety, strength and durability for its intended use. The requirements set out were chosen
to ensure compliance with these considerations. Where buoyant swimming devices are provided in
several components, the requirements apply to each of the components as specified in the relevant
paragraphs below.
Buoyancy may be provided by inherent buoyancy materials, by inflatable chambers or by both. Where
buoyancy is not inherent, devices shall have a minimum of two independent chambers safeguarding
function and to allow the user to maintain the airway above water level at all times if one chamber fails.
A device shall be only class A or class B or class C.
These products shall be manufactured in bright colours that are in contrast to the water surface so as to
be visible at all times and at any angle when in use. Wholly transparent or materials in any shade of
undecorated blue in the visible areas when in use are not acceptable.
For safety reasons and to assist in supervising children when used in the water, the visible areas of
these products when being used shall be clearly visible from the water‘s edge or the poolside when the
water is crowded, moving or may not be clear. Where criteria cannot be objectively assessed, they shall
be subject to evaluation by the assessment panel.
The assessment panel shall agree, by at least a 2:1 majority or by unanimity, that the device is visible
when used in the water.
